[Bug 879662] Re: installer crashed with IOError: [Errno 2] No such file or directory: '/target/usr/sbin/policy-rc.d' during system installation

[Ed Wetmore]

This problem is easily repeatable for me, and I have discovered a workaround as well. 
I have 2 systems on which I have installed Mythbuntu 11.10, the issue occurs on one but not the other.
For the system on which it occurs, the process begins by having an installation of Ubuntu or Mythbuntu already in place.
When I select "something else" from the disk partitioning choices, and if I intentionally delete the already created fdisk partitions that the previous Ubuntu/Mythbuntu occupies and then recreate the partitions, the problem does not occur. The failure always occurs when the installer is migrating files if I do not manually delete the existing Linux related partitions from the previous installation.
The system that this happens on was already configured to multiboot in to MS Windows, Solaris 10, and at least 1 distribution of Linux. The Linux installation has /boot on the BIOS disk0, and the swap and / file systems are on the BIOS disk1. While I had no issues when I first installed Mythbuntu 10.10, the crash first occured with Mythbuntu 11.04, and repeated with Mythbuntu 11.10. Since I chanced on the workaround with the 11.04 installation, I guessed that the problem was something related to my hardware configuration and I aborted the installers attempts to post the installer crash. When the 11.10 installation crashed also, I allowed it to file it's report.
I can provide more detailed system hardware information, but I'm beginning to wonder if the system age is beginning to show.
